The monitor spindle damping strength can be adjusted?
Rotary axis in the damping strength can be adjusted, turning hard may be too much damping strength of the reason or lubrication reasons, to my understanding of the rotary axis, you said the rotary axis is not to be replaced, it is recommended that you go to the after-sales repair, or re-exchange can be a while ago heard a, Soksing rotary axis, do this, I recommend that you go and ask them, they may be more clear than I would.
